HARRY E. nonvmnor Annnnson, INDIANA, ASSIGNOR, BY mm: ASSIGNMENTS, T

GENERAL morons CORPORATION, or person, MICHIGAN, A conrom'rron or DELAWARE.

To whom itmay camera:

Be it known that I, HARRY E". Nouvmt,

aycitizen of the United States of America, residing at Anderson, county of Madlson, State of Indiana, have invented certain new and useful Improvements in Switches, of

which the following is a full, clear, and exact description.

lhis invention relates to electric swltches 1c and particularly to switches for controlling the lighting and ignition circults of automobiles.

It is an object) on the invention to provide a switch which has a lass front for w the punpose of protecting t e dial and-so that the switch will compare favorably in I appearance with other instruments of the automobile on the dash board such as the W for clamping the switch to the dash board. I

In'this connection, it is a further obJect to provide switch clamping means which can be used to secure switches to dash boards of varying thickness and of different materials, for example to a thin metal dashor to a a thick wooden dash.

Another object is to provide a switch having its terminals so located that wires can 'be attached to all of the terminals without turning the switch around or upside down. v Another object is to locate the switch terminals so that either a dimmer resistance or a vibratory short circuit indicator can be mounted on the back of the switch.

A further object is to provide aswitch in which the total number of parts and number of different pants has been reduced to the minim-um, thereby effecting economy in manufacture.- A further object isv to provide a switch in which the enclosed parts are readily accessible for repairs and adjustments. r

Further objects and advantages of the present invention will be apparent from the 60 following description, reference being had to the accompanying drawings, wherein a preferred embodiment of the present invention is clearly shown.

Fig. l6 is a fragmentary side view thereof looking in the direction'of arrow 16 in ig. 17 is asimilar view looking in the direction of arrow 17 of Fig. 14;

Fig. 18 is a side view partly in section showing the switch attached to a thick dash board; and I 1 Fig. 19 is a similar view showing the switch attached to a thin dash board. heifer-ring to the drawings, a switch cas mg 20 is provided with a flange 21 having spaced notches 22. Generally speaking the casing 20 is cup-shaped its end wall 23 having a boss 24 extending therefrom said boss having apertures 25; 26, and 27 and arcuate notches 28 and 29 and recesses 30, 31, and 32. Casing 20 is also provided with tapped holes 33, 34 and 35 and with lu 37 and 38, the latter having a threade connection therewith. Apertures 26 and 27 provide shaft bearings.

Casing 20 supports dial 40, glass front or dial cover 41, gasket 42 and bezel rin 43. Ring 43 is provided with ears 44 whic are bent around flange 21 of casing. 20 into notches 22, to hold the dial, gasket and glass in place. Dial 40 and glass 41 are each provided with apertures aligning with ap ertures 25, 26 and 27 of casing 20.

A look cylinder 50 is rotatably supported Within aperture 25 and is controlled by key 51. Lock cylinder 50 is provided with a flange '50 which overlaps the hole -in glass front 41 through which cylinder 50 extends.

. Cylinder 50 projects through locking plate 53, and carries at its inner 52 having a lug end a thrust plate 54 having portions 55 and 56 adapted to engage the lug 53. Lockin plate 52 is provided with a locking ln 5 I and with depressions 58 and 59 with w ich a spring pressed dog 60 slidable in recess '32 1 cooperates. Locking plate 52 slides between ridges 48 and 49 extending above boss 24 of casing 20.

Ignition switch handle 61 has a cylindrical hub 62 rotatable within aperture 27, and hub 62 carries pins 63 and'is provided with a flange 64 overlapping the vholein glass front 41 through which the hub 62 projects.

Pins 63 of hub 62 support insulating washer 65 having holes 66 to receive said pins 63-, and also notches 67. A contact blade 68 is supported on washer 65 by means of blade clip 69 having prongs 70 extend ing through holes 71 in blade 68 and into notches 67 of washer 66. The parts 69, 68

and 65 are held on hub 62'by means of screw 72 passing through these parts and screwing into hub 62. Screw 72 is insulated by.

washer 73.1 The washer 65 constitutes a reversible locating member having two sets 65. The contact 68 is provided with the holes 71 which are diametrically located and spaced 'to align with the notches 67.-- The clip 69. provides a connection for contact 68 with washer 65 in either a position such as shown in Fig. '11 or in an inverted osition. Hence it is possible to provide for ocating the contact 68 with respect to the hub'or shaft 62 in four positions of location. Two

of these positions are apparent from Fig.5.

This construction and arrangement permit the use of the same jacent shafts.

Between hub 62 and washer 65 there is located a ratchet plate 74 transverse to the shaft'or hub 62, said plate having its surface corrugated to* provide detents 75 adapted to be engaged by a spring ball 76 located in recess 31, said pate 74 contact piece on two ad-' pressed being turned by hub 62 through pins 63. Plate 74 is provided with looking notch 77 to be engaged by lug '57 when the ignition switch handle is in the off position as shown.

81, 82 and 83 for'making contact in a manner to be described.

The light switch handle 61 carries parts like those carried by handle 61 and these parts and other parts cooperating therewith are designated by similar numbers but with a prime afiixed. .Thesesimilarly numbered parts are alike, it being apparent that .parts 65', 68' and 69' have been diiferently located with respect to the hub 62' of handle 61". differently from plate 74. The lug 78 of plate 74', cooperates with arcuate recess 28 (Fig. 6) to limit the movement of handle 61. Plate 7 4 is not provided with looking notches, but these could be provided where desiredto' cooperate with a locking lug on pl'ate 52 similar to the lug57.

Switch casing back or terminal block 90 is mounted on the casing 20 by screws 91;

The ratchet plate 74' is also located 92 and 92 engaging holes 33, 34 and 35 respectively in casing 20. Block 90 supports battery terminals 93 and 94, ignition terminal 95, curb light terminal 96, bright or large head light terminal 97, dim or small head light terminal 98 and tail light terminal 99. These terminals 7 by flat headed rivets 93' to 99' inclusive respectively, (represented by dash line circles in Fig. 3) and in some instances these rivets serve as stationary switch contacts. These terminals are arranged so that the screws for attaching wires thereto may be accessible to a screw driver from the top or sides of the switch, the screw driver being held substantially parallel to' the back of the switch with its blade either pointing downwardly or in a substantially horizontal position. The switch need not be inverted to render the terminal screws accessible from above the switch. This arrangement of terminals I however requires that the terminals in some instances be connected by straps with other flat-headed rivets in order that the stationare held in place ary contacts may be correctly located in circles to cooperate with blades 68 and 68 which are alike but difie'rently located. Terminal 93 is connected by strap 100 with contact rivetlOO; terminal 96 is connected by strap 101 with contact rivet 101'; terminal 97 is conneced by strap 102 with contact rivet 102'; terminal 99 is connected by strap 103 with contact rivet 103"; and teriao .minal 94 is connected by strap 104 with conhandle 61' is turned to bright position, finger 83 touches 104:, finger 81 touches 103, and finger 81 touches 102' thereby con- 7 necting battery terminal 94 with tail light terminal 99 and bright light terminal 97. 1f. handle 61? is turned to curb position, finger 83' will touch 81', fin er 82' will touch 99 and fin er81' w' touch 101' thereby connecting attery terminal 94 with tail light terminal 99 and with curb lightterminal 96'.

In some installations a jumper 110 connec'ts terminals 94 and 93. Where an overload circuit indicating device is included in the battery circuit (such as described in the;

patent to f}. F. Kettering, No. 1,336,143 dated April -6, 1920) this device is mounted on a bracket riveted to the switch back 90 means of rivets passing through holes 111 and 112, and the terminals of the device are connected with 94 and 93, the jumper 110 being omitted, If instead of'dim or small head lights, the equipment provides only large head lights and a dimmer resistance to be inserted in the head light circuit,

' As shown in Fig. 2, ring 120 has an out this resistance is connected between terminals 97 and 98. if no overload circuit indicator is mounted on the Switchback, then a support for the dimmer resistance may be mounted in its place.

The manner of mounting the switch to thick and thin dashboards is shown in Figs. 14 to 19. A finishing ring 120 serving as a clamping member is located between the flange 21 of casing 29 and the dash 118.

,wardly extending flange .121 abutting dash 118 and an inwardly ertending'flange abutting flange '21 of casing 20. A reversible --=clam ing ring 123 is provided with an out- .ward y extending flange 12d having tap ed holes 125, 126, 127 and 128, and'is provi ed .with an inwardly extending flange 129 having diametrically opposite depressions 130, 131 on the outside thereof, and diametrically opposite depres'sions'132, 133 on the lnslde thereof; N0tches-134'and 135 are provided sothat the ring 123 can he slipped over lugs 37 and 38 of casing 20.

To clamp the switch to thick woodeii dash 118 the flange 129- of ring 123 is located nearest the dash 118 and the ring'123 is turned so that lugs 37 and 38 may engage is available for she w the depressions and 133 on the inner side ofv flange 129. Screws 140 threading through holes 125 and1126enga e thrust ring 141 which bears against Therefore dash 118 is clamped between rings 141 and 120. I

To clamp the switch to thin dash 119, the ring 123 is reversed so that flange 124 is nearest the dash 119 and lugs 37 and 38 seat in depressions 131 and 130, respectively. Screws 140 pass through holes 127 and 128 and bear directly against dash 119.

ash 118.

It is therefore apparent that the dash board need be provided only with a large round opening to receive the switch. lhen only two clamping screws are necessary to secure the switch upon the dash. The same clamping parts can be used to clamp the switch to thick or thin dash boards, and

wood or metal dash boards.

When the switch islocated upon the dash board it presents an appearance comparing favorably with the other instruments on the dash, such as the speedometer, by reason of,

its glass front which protects the dial and allows the switch face to be easily cleaned without wearing oh the switch dial by repeated rubbing}. 1

"1n putting oles in the glass front the edges of these holes may appear unsightly. These edges are covered by the flanges 64,

6 1 and 50. of the handle hubs and lock cylinder thereby eliniinatinaccurate finishing of these holes; These :5? anges also assist in preventing dirt entering the switch casing.

It is difierent switch parts has n reduced since the movable parts of the light and iition switches are the same with the exception of the ratchet plates which use the same punch- ][n case also apparent that the nber of lot ings. a

the lettering is a plied to the dial by radium paint or ot er luminoris paint, the glass front will protect this paint from being rubbed or clipped oh".

1n the 0 position switch handles 61 and 61 extend vertically and these handles are made thin as shown, in Fig. "1, in order to keep visible a space on the dial large enough to show the name of the car. The space between the switch handle hubs and the lock g the name of the switch maker. 1
